When the fan are spinning too loud, it can be due to:1. Wrong system fans are connected on the board.2. Incompatible chassis and wrongly configured SDR.3. Compatible chassis with a wrongly configured SDR4. Bios Settings wrongly configured.

I will personally try to check if the chassis is on the compatibility list and the system fan headers are correctly connected.

Extract the zip files.Copy all the extracted contents in the folder to a FAT-FORMATTED USB (ROOT DIRECTORY of the usb)Insert the USB to the target machine.Boot the system into the BIOS (F2)Go to Boot ManagerSelect the EFI Shell and press EnterIt will automatically boot onto the EFI shell.Once on the EFI shell, the shell will look for the file startup.nsh automatically in the USB.If it does not find the startup file, try another USB.It will load the firmware package automatically and you just need to follow the instructions.

If you have the right 4-pin power connector is connected onto the board, then it wont ask you for the chassis.

Anyway if it asks you, make sure to choose the correct chassis when doing the SDR firmware update. Follow the instructions.

After the update of these firmware, i will go onto the bios and Advanced, System Acoustic and Performance Configuration, Throttling Mode set to Open Loop, Set fan profile as Acoustic and Altitude set 300 or less.

Other than this, next steps will be to verify the sel log and verify the release notes of the firmware if there is anything mentionned.

If it is not solved, let me know these:which OS do you have?Does the fan speed slows and only in the OS it increases?

Thank you very much. I followed your instructions from beginning to end, and it resolved my issue. I believe the problem was due to incorrect chassis fan connections as I had already updated the BIOS, BMC, and FRUSDR.

For future reference, the fans turned on full speed as soon as the system was powered on, and did not ever slow. The operating system used was Windows XP 64bit.

I also have problems with fan control with my S5520SC main board. I did update to the latest BIOS, Firmware, FRUSDR. When came the time to update the the FRUSDR, I got a warning like what the Temperature Sensor of the Front Control Panel couldn't be found and it was necessary to control the fan speed. At the end of the FRUSDR update, the fans slowed down for a few seconds, but went up to full speed shortly after. Now the fans are always running at full speed.

The case I'm using is a TITAN 650 by Antec and it effectively doesn't have a temperature sensor. After searching the Internet, I found out that the Intel case SC5600BASE (approved case for the S5520SC board) uses the following Front Control Panel (FCP): FXXRIGTFPBRD and optionally the following Local Control Panel (ILCP): AXXLCPPED. I know some ILCP have temperature sensors that communicate the temperature to the motherboard through a one wire connection.

My question is :

If I install Intel ILCP will it resolves my fan speed problem - does this one includes a temperature sensor that connects to the board? Has anyone ever tried ? Any comments would be welcomed before I spend money on this device.

The Chenbro SR105 case is on Intel's "tested" list. I found no documentation though on how to properly configure/ integrate the case with this motherboard. (Three days wasted, I am beginning to regret my decision to put my trust in Intel.)

This hasn't solved our issue. We are running the same case, SC5650WS. The rear fan runs at full throttle from startup. There is only one place to plug it in according to the instructions (Fan 5 I think) It has the current BIOS, SDR, Firmware, etc installed from the bootable CD and internet connection. The other fans are correctly connected (the only nebulous area are the 2 front case fans have 4 places to plug them in, we have tried both on the left and both on the right. They have white connectors, so we tried the white connections first, then the blue to no effect.)
